Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

I'm attempting to install a plugin to my android device to test it with web-ext, but I'm getting the error `No Firefox packages were found on the selected Android device`. Running verbose, I found it running `adb shell pm list packages`, so I ran it myself, and got the next error `Shell does not have permission to access user 10`. I have to manually specify in the command to use user 0, but I am unable to do that with web-ext as far as I'm aware

phone: SM-A13 Android version: 13 OS: Linux Ubuntu web-ext version: 7.11.0

For the last week, Thunderbird hasn't downloaded the mails from my Strato account. I can still send mails, and read the mails when I log in to Strato. Thunderbird still downloads the mails from my other accounts. It worked fine until now, so I suspect the problem is related either to an automatic Thunderbird update or an automatic Windows (10) update.

Yesterday, whenever I tried to open Thunderbird I got a This app will not open on your PC Windows error, and Word and Excel would not work. Apparently I had some Windows 10 problems which I was able to repair with Windows Resource Protection. Thunderbird now runs, but all 2000 of my Inbox messages do not appear. If I open my Mail folder in my Profile, I see the four folders inbound.att.net, inbound.att-1.net, inbound.att-2.net, and inbound.att-3.net The size of each of these inbound Mail folders is 5MB, 9.8GB, 38MB and 20MB. So, all of the missing Inbox emails are in the inbound.att-1.net folder but they don't show up. I tried deleting the .msf file. That didn't help.

Does anyone have any suggestions?

Private tabs disconnects the second I switch to another app or turn off screen. And when I switch back tabs basically opens again. So if I try to listen to a podcast from a private tab, it will stop, if there was any data typed, it will be lost. I disabled all power saving settings on the phone, it didn't help. And I didn't find anything in Firefox settings I'm using redmi note 10 with miui 14 global. Firefox from Google play. And UBlock and Privacy Badger are installed

Running Firefox 125.0.1 on MacOS 14.2.1, all audio input is very quiet for all applications, not just Firefox.

Experiments I ran:

• people can barely hear me in Google Meets
• microphone works great in Quicktime (making a recording) when Firefox is running but not receiving audio input
• microphone is very quiet in Quicktime when running a Google Meet in Firefox
• microphone is very quiet in Quicktime when running a discord voice channel in Firefox
• microphone works great in Quicktime when running Google Meet in Chrome

This started maybe ~3 months ago for me. I'd love to see a fix, since Firefox is my favorite browser in most other ways - otherwise I'll have to give up and switch to Chrome at long last :'(

Hello, I hope that this question is taken at face value. I Have tried working with the new UI since it was pushed and as of today I have had enough and I have reverted back to 102. there are a number of issues that have still not been addressed or fixed in 115 or 125 but the thing I keep finding increasingly infuriating is the UI. I understand UI is personal taste for some however for productivity changing the UI can be disastrous. it has been months since the release of 115. And the amount of time I have wasted because of the new UI is staggering. it is (to me and from what I am reading MANY others) extremely un-intuitive and tedious to use. I will not mention all the performance issues here as they are a separate issue. I would have liked to see an option to use the previous (read standard / tried and true) UI but since they did not, they appear to need an incentive to do such, so as the subject asks how much will it cost to add an option to revert the UI and how can we annotate that we would like it reverted as the donation page does not allow for notes or requests, and obviously the current leadership has a vision that is not in line with many users expectations.

I would like to reiterate this is not an attack on people who do like the new UI but a simple fact that many people appear to not like it and would like to be able to continue using the software both up to date and with a UI that actually makes sense to them since email clients have been virtually the same for over 2 decades now and that look and feel has become the de-facto standard in the industry for a reason.

TLDR: new UI is no longer intuitive to "industry standard" applications and I want to know how much it will cost to bring that back.

Hi there,

I'm curious if it's possible to configure Firefox on your own to make it a portable browser. Specifically, I want to disable data encryption and machine ID checks. I know that some chromium-based browsers allow you to do this through specific switches that turn these features off, resulting in a fully portable browser. While I'm aware of third-party applications that offer ready-made solutions, I prefer not to use them for security reasons. I'd like to prepare my own version of Firefox.

I understand some may have security concerns, but I know what I'm doing. The files will be stored on an AES256 encrypted drive. Could anyone share insights or guides on how to achieve this with Firefox? Thanks a lot

PS.For those who might suggest using synchronization, I assume that, similar to Chromium, Firefox can't sync all plugin settings, and for me, plugins are essential—without them, it's not really a browser.

I need the option to convert message date to local time on forwarding, instead of UTC + - from the original header.

This is the expected behavior in every other client I have used.

Even if the original sender is in the same city as me, chances are their originating server could be somewhere else and their originating time preference may not be set correctly. So it's more useful and logical to end user to show that in my local time zone.

Please, at least make it a user preference option.

I am not the only one:

Hi, i searched i have the same problem as last comment https://support.mozilla.org/mk/questions/1415834

This solution does not work. Firefox on Android will display a "Did you use the system camera? You must pair from within the Firefox app." when selecting the QR scanner from the dialogue box in Firefox. The option is still missing in the menu as well.

Dear Firefox community,

in the bookmarks page on iOS devices, Why can't we swipe back to the previous state and we have to press the previous arrow, Is it an issue or just something else?

Would want to make this post along time ago but I thought users and developers would notice it.

really appreciate it

best regards,

I'm having a really annoying problem where Calendar events, even tho they have reminders/notifications properly set up, just don't actually trigger these notifications when they're supposed to.

Are there any logs or debug settings or anything I can do to troubleshoot this further? All of the direct UI settings are definitely set up correctly. And there are other events for which notifications work fine, so it's not that notifications are broken altogether

Tbird is close to perfect for me, so I regularly support it. One thing I do have occasional problems with concerns searching and using tags I hope I am wrong, but when I search for one or several emails I usually find them, but still have no idea of where they are located. The same applies to the very handy tags which I also gratefully use. I filter mails to appr 30 folders and archive them yearly, so actually finding an email can take some time. The path to the folder is not necessary - just the name of the folder would be enough to pinpoint it

Thunderbird Version 115.10.1 on Windows 10

I wrote my own POP3 server and it largely seems to work apart from when Thunderbird tries to RETR the email messages at which point I get the error "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.".

If I drag a saved version of that same email that fails to be retrieved into Thunderbird , it can write it to the Inbox without issue. That means Thunderbird has permission to write to the Inbox file and so it is not a permission issue and there is enough space. I feel like it is more likely to be something I am doing wrong in my protocol implementation. For example, could I get this error if I misrepresented the octet count? Also I notice that even though my CAPA reply does not include UIDL, Thunderbird still seems to send that request and should get the response "-ERR Unknown command".

Output from my server showing what Thunderbird sent to it: CAPA USER person@mydomain.com PASS XXXXX STAT LIST UIDL RETR 1 QUIT

Any help is much appreciated, even if it is guidance on how I can debug it more thoroughly.

Thanks.

I created a compressed (zip?) file from my prior computer. I have not been able to figure out how to get the data from that file onto my new computer. My primary need is for my tasks and events calendar. I have been able to access email accounts without referencing the compressed/zip file. When I insert the flash drive, a message pops up asking me to "insert the last disk of the multi volume set" I don't understand this request. Thanks in advance for any help you can give me

I have been using Thunderbird for years. Always updated to the latest version. My current Thunderbird addresses are setup through Hostgator hosting and I've rarely had an issue. I recently set up a Zoho email address and added it to my Thunderbird platform so I can send and receive emails there. Problem is, when I send a test from one of my long time Thunderbird emails to the new email that goes through Zoho, it never shows up in my Thunderbird inbox. Never shows up in my Zoho inbox either. I can send from the new Zoho email to one of my established emails no problem using Thunderbird. But it doesn't work the other way around. I've checked everything I can think of--IMAP server settings, SMTP settings, added MX records, you name it. Not sure where the hang up is. Hopefully someone can help, thanks.
